1 Claim.

This invention appertains to new and useful improvements in power drills and more particularly to drills of the drifting type.

The principal object of the present invention 5 is to provide a drill mount whereby the drill can be adjusted horizontally and vertically with ease as well as swung in a horizontal arc to meet various requirements.

Another important object of the invention is to provide a drill mount which will positively retain the drill sturdily without likelihood of self displacement.

Still another important object of the invention is to make various quick adjustments of the drill proper without any manual exertion or delay of time.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a fragmentary side elevational view showing the drill in its mount.

Figure 2 is an enlarged fragmentary vertical sectional view.

Figure 3 is a fragmentary side elevational view of the drill mount;

Figure 4 is a fragmentary side elevational view of the horizontal supporting bar.

Figure 5 represents a fragmentary side elevational view of the vertical supporting post.

Figure 6 is a plan view of the lever and notches shown in Figure 2.

Figure 7 is an enlarged sectional view on line l''l of Figure 2.

Figure 8 is a cross section on line 88 of Figure 4.

Referring to the drawings wherein like numerals designate like parts it can be seen that numeral 5 generally refers to the drill proper with the tool 6 extending therefrom.

Numeral represents the carriage for the drill 5, the drill 5 being slidable thereon and controlled by the screw shaft 8 equipped with the crank 9.

Numeral l denotes the. usual vertical support- 45 ing post for the drill 5. The horizontal supporting bar is denoted by numeral ll, one end being constructed to form one half section of the jacket generally referred to as numeral l2. These sections are denoted by reference character ab and are hingedly connected together as at 13. The jacket I2 is provided with the detent generally referred to by numeral I4 and while this detent is retracted to permit rotation of the jacket I2 on the post 10, the collar generally referred to by numeral l supports the jacket and bar H.

As is clearly shown in Figure 5, the vertical post 10 is provided with groups of circumferential recesses [6 within each of which are the teeth I1. Each group consists of two of the recesses l6 one for the detent M of the jacket I2 and the other for the detent l8 on the collar IS.

The horizontal bar H has circumferential extending recesses or reduced portions l9 each of which is provided with teeth on the bottom thereof and these recesses 19 are equidistantly spaced along the rod II.

The carriage 1 is provided with the depending headed stud 2|, the head 22 of which is received by the socket structure 23 on the collar 24 which circumscribes the bar II. The lower portion of this collar 24 is provided with a recess 25 therein for receiving the slider 26. This slider 26 is provided with teeth thereon to mesh with the teeth 20 in the recesses 19 of the bar I I. This slider 26 has the rigid screw 2'! depending therefrom through an opening in the bottom of the socket 25 and is received by the nut 28 operating within the confines of the bracket 29 on the bottom of the collar 24, this nut 28 being provided with an outstanding handle 30 which when swung from one point to another will feed the screw 21 upwardly along with the slider 26 so as to engage the teeth of the supporting rod H. A swingable spring pressed detent 3| at the free end is engageable into recesses 32 in the bottom of the bracket 29.

A similar form of detent is shown for the stud head 22, wherein the stud head 22 is provided with circumferentially arranged teeth 33 with which the toothed plate 34 is engageable, said plate being provided with a screw extension 35 fed by the nut 36 which has a handle 3'! and the retaining pawl 38. Obviously the collar 24 supporting the carriage I can be slid to any point desired on the rod II and retained in that position and obviously by operating the nut 25, the carriage can be freed so that it can be swiveled on a given plane.

The detents l4 and I8 are constructed in substantially the same way as the detents described in detail in Figure 3 as generally referred to by numeral 40.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

and the collar, said detent means consisting in the provision of circumferential reductions on the upright and arm, teeth on the bottoms of the said reduoements, and toothed followers on the jacket and collar feedable into the said reducements to engage the teeth therein.
